Basic WebSocket Server in Rust

A lightweight, asynchronous WebSocket server implementation using Rust and Tokio.

Features

• Asynchronous WebSocket communication
• Echo server functionality
• Connection management with proper error handling
• Built with Tokio and Tokio-Tungstenite

Architecture

The following flowchart illustrates the server's operation:

Requirements

• Rust 2024 edition
• Cargo package manager

Installation

Clone the repository and build the project:

git clone https://github.com/LinuxUser255/websocket-server.git
cd websocket-server
cargo build --release

Usage

Run the server:

cargo run

The WebSocket server will start on ws://127.0.0.1:9001.

Testing the Server

You can test the server using various WebSocket clients:

• Browser-based clients like WebSocket King
• Command-line tools like websocat
• Write your own WebSocket client

Example with websocat:

websocat ws://127.0.0.1:9001

Type messages and they will be echoed back to you.
